ABSTRACT:
A method and system for detecting a condition indicative of a chain jam in a power driven endless chain are disclosed. The chain of such a system is forced into a zigzag pattern by the inclusion of deflectors at various positions along the chain pathway and the force exerted against these deflectors is measured by sensors. When a jam occurs the force on the deflectors between the location of the jam and the drive, in the direction upstream from the drive, increases, and this increase is sensed and used to actuate indicators near each of the sensors at which such an increase has occurred. The chain jam is found upstream of the furthest actuated indicator from the drive.
